How much you can still eat listed foods
In Finland we have the same kind of tracking site then this named Sulamo. They have a function to say how much you have to eat and what food to get all needed micronutrients. an example you still need 20% of vitamin-A you put your cursor over it tells you what you can eat and how much you have to eat to get needed amount. Its work like your oracle but it gives you more defined answer to your question. Is it possible to do same in your software?
ps. Your software is way better in other parts than Sulamo
